Today’s newest external enclosure designs are based on architectures that support both SATA and SAS drives. The MegaRAID SAS 9280-8e, with eight external SATA+SAS ports, is ideal for configuring these external enclosures with your choice of high-performance SAS hard drives, high-capacity SATA hard drives or energy-efficient solid state drives (SSDs). With data transfer rates of up to 6Gb/s per port, the MegaRAID SAS 9280-8e bring users new features and improved performance, while continuing to support all the features of the previous 3Gb/s SATA+SAS generation. This feature line controller employs the latest in RAID-on-Chip technology, complies with the PCI Express® 2.0 specification and provides additional data security using LSI™ SafeStore™ encryption services.
